+xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661).
+L2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user
+sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP
+servers. Another important application is Virtual Private Networks where
+the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec,
+RFC 3193). The L2TP/IPsec protocol is mainly used by Windows and
+Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec
+implementations such as Openswan.
+Example configuration files for such a setup are included in this RPM.
+
+xl2tpd works by opening a pseudo-tty for communicating with pppd.
+It runs completely in userspace but supports kernel mode L2TP. 
+
+xl2tpd supports IPsec SA Reference tracking to enable overlapping internak
+NAT'ed IP's by different clients (eg all clients connecting from their
+linksys internal IP 192.168.1.101) as well as multiple clients behind
+the same NAT router.
+
+xl2tpd supports the pppol2tp kernel mode operations on 2.6.23 or higher,
+or via a patch in contrib for 2.4.x kernels. Note that kernel mode and
+IPsec SA Reference tracking do not yet work together.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.

+xl2tpd: xl2tpd (L2TP daemon)
+xl2tpd:
+xl2tpd: Xelerance Corporation currently maintains a version of the Layer 2
+xl2tpd: Tunneling Protocol (L2TP) daemon. 
+xl2tpd:
+xl2tpd: This version contains many patches that have not yet been integrated
+xl2tpd: into the mainstream release. These patches are needed to run on
+xl2tpd: modern distributions with DEVFS, or to support L2TP over IPsec, when
+xl2tpd: used in conjunction with Openswan.
